It's been so long since I had to use one of these, that I've forgotten some of the details, and I don't want to blow up or damage either this unit or the battery.

As indicated I have a Singer-Graflex Booster Analyzer, catalog # 2095, which has the ability to test the voltage of the various dry cell batteries used in the Graflex HV battery cases (in my case the 250 and 500) and to also boost the battery to extend it's longevity.

It also has the ability to test the status of the capacitors in the power heads of the 350 and 500 (and perhaps the older Strobomatic units using the proper adapter's)

So my question to the fine readers of this group is: does anyone remember using this unit in the past, or uses one currently that could impart some tips or suggestions.

I have a 510 VDC battery that is in need of a boost, but I wanted to seek some advice before I end up launching the battery into space or perhaps damaging the unit.

As always I appreciate any advice or suggestions that you might wish to share with myself or other readers.
